Definitions

  • This spotlight is mainly designed for the lighting of swimming pools in a water-submerged state, but it can also be used for ornamental fountains and even as a light projector outside the water.
  • PAR 56 parabolic lamps having been used for some time now which are known as "PAR 56" and are formed by a body and a lens being both made of glass, said lamps comprising as a light-emitting element an incandescent filament bulb, the body having an inner metal coating serving as a reflector.
  • LED's have been recently used instead of the bulb, said LED's possibly being of different colours such as for example red, blue and green, in order to thus obtain different lighting combinations, the body being made of metal and the lens being made of glass.
  • the object of the invention is a submersible spotlight of the type comprising as light-emitting elements LED's possibly being all white or of different colours.
  • This novel light-emitting spotlight represents a notable improvement to the manufacture of this kind of submersible spotlights, a feature lying in the fact that the body and the glass are each obtained as a moulding being made of plastics material and peripherically welded together, their manufacture being thus sensibly simplified and their cost being thus more reduced, both members thus forming a solid and undeformable assembly.
  • low-power LED's are used in a greater number than usual.
  • the electric connections of the spotlight are arranged at a hollow pillar being provided at the centre of the body and having an outer open end.
  • this submersible spotlight comprises a body (1) and a transparent front (2) (lens) being made of plastics material, both parts being welded together and thus tightly fitted to each other in a sealed arrangement.
  • the body (1) is concavely shaped, and the printed circuit (4) with the LED's (5) connected to it is securedly attached to said body at this latter's open front end and by means of screws (3).
  • an inner pillar (6) forming a hollowed-out portion (7) with an outer open end (8) being fit to receive a stopper (9) that will be tightly fitted to it in a sealed arrangement and comprises sockets (10) and (11) for the electric connection of the spotlight.
  • This submersible spotlight has the format of the "PAR 56" parabolic lamps and is hence in a position to replace them and to thus produce the aforementioned multicolour effects while at the same time notably reducing the power consumption and reaching a longer duration.
  • This spotlight can form part of a lighting system being actuated by a radio remote control.

Claims (2)

  1. Une lumière étanche constituée d'un corps (1) avec une façade transparente (2), les deux parties sont faites en matière plastique et sont périphériquement soudées entre elles, et de plusieurs LED (5) comme éléments émetteurs de lumière. Elle se caractérise par le fait que le corps (1) a une forme concave et, le circuit imprimé (4) et les LED (5) sont connectés de façon sure au corps, à son extrémité frontale, par des vis (3). Ce corps(1) a, dans son centre, un pilier intérieur (6) qui a une portion creuse (7) et une extrémité extérieure libre (8) adaptée pour recevoir un bouchon (9) qui sera fermement ajusté à celle-ci par un dispositif de scellage et qui comprend les connexions électriques de la lumière (10, 11) qui y seront ajustés.
  2. Une lumière étanche selon la revendication antérieure caractérisée par le fait que les LED (5) sont de différentes couleurs.
